David discovered a bug which gave memory corruption because the tx_buf was written past its end for st7586 which has a smaller tx_buf. The problem was that mipi_dbi_enable_flush() now calls directly into mipi_dbi_fb_dirty() instead of going via the tindyrm_device dirtyfb callback. Changes: - Include vblank header (Sam) - ili9225 and st7586 can't use mipi_dbi_enable_flush() (David) Noralf.
